This collection of Genuine Dinosaur poop came from a Utah fossil dig, Emery County, Utah, Jurassic Brushy Basin - Morrison Formation in Utah, 155-147 million years old. The Morrison Formation covers 600,000 square miles in several states, the most fertile source of dinosaur fossils in North America. The coprolite has been made into beads.

When it fossilized, the coprolite was replaced with natural minerals in the sediment around it, turning it into colorful jasper and agate. The original shape of the coprolite remained.
